In a system including a robot and a controller controlling the robot, the controller switches the robot from a first state to a second state in which orientation change in accordance with external force applied to the robot is more tolerated than the first state based on detection of contact of an object with the robot. The controller switches the robot from the second state to a third state in which the orientation change in accordance with the external force is more restricted than the second state after the orientation change in accordance with the external force applied to the robot is started and while the external force is being applied to the robot.

System, manufacturing method, controlling method, program, and recording medium

A robot apparatus capable of performing a stable wireless communication is provided. The robot apparatus includes a robot arm including a link, a first control device disposed in the robot arm, a second control device, and a wireless communication unit configured to enable the first control device and the second control device to communicate with each other wirelessly. The wireless communication unit is disposed in the link.

Robot apparatus, control method for robot apparatus, method of manufacturing article using robot apparatus, communication device, communication method, control program, and recording medium

A driving apparatus includes a movable portion, a fixed portion configured to hold the movable portion, and a controller configured to control a position of the movable portion relative to the fixed portion. At least part of the outer surface of the movable portion is a spherical surface. The fixed portion includes a plurality of vibrators configured to press and contact the spherical surface of the movable portion and to rotate the movable portion, and a pressure receiver configured to hold pressure contact states of the plurality of vibrators against the movable portion. The movable portion is held by the plurality of vibrators and the pressure receiver, and a spherical center of the spherical surface of the movable portion is located between a plane passing through the plurality of vibrators and the pressure receiver.

Driving apparatus

In an image capturing apparatus that allows input of instructions to the image capturing apparatus by shaking the apparatus, without using an operation unit, it is determined whether or not the image capturing apparatus is shaking. Then, in a case in which it is determined that the image capturing apparatus is shaking, at least some of the operations of the operation unit are invalidated.

Image capturing apparatus and control method thereof

An imaging apparatus with an image sensor and a correction optical system movable in a direction perpendicular to an optical axis includes a vibration detection unit configured to detect a vibration applied to the imaging apparatus, a vibration correction unit configured to drive the correction optical system to correct an image vibration according to an output from the vibration detection unit, a motion vector detection unit configured to detect a motion vector based on an image signal output from the image sensor, an amplifier unit configured to amplify the output from the vibration detection unit, a gain setting unit configured to set a gain of the amplifier unit based on the motion vector; and a gain control unit configured to allow or inhibit the setting of the gain of the amplifier unit set based on the motion vector, according to a change of an imaging condition of the imaging apparatus, wherein the vibration correction unit performs a vibration correction based on the output from the vibration detection unit and the gain of the amplifier unit when the setting of the gain of the amplifier unit is allowed by the gain control unit.

Imaging apparatus for stabilizing an image

An optical apparatus capable of detecting an attitude of the apparatus in a state where no interference occurs between apparatus components, thereby preventing an error in the attitude detection. A shift lens drive controller of the optical apparatus detects a shake applied to the apparatus, calculates a movement target position of the shift lens based on a result of the detection, detects an actual position of the shift lens, and performs feedback control such that the actual position of the shift lens is converged to the movement target position. An attitude detector detects the attitude of the optical apparatus by using feedback control information, and an interference prevention controller prevents interference between the shift lens and other members.
